' The invention described and'claimed here in is an improvement on the structure shown and. described in a priorpatent' granted tome I October 23,1928, and bearing Patent No.;1,- 688,349. In my present invention I have'devised means for adapting the broad principle structure of more or less conventional form,

. so as to render. this conventional type of whis;

tle more sanitary and practical in use. and also simplifyv the .manufacture thereof. f The particular type-of whistledisclose'd in] the accompanying drawing is of the substantiallycylindrical type wherein the'mouthpiece projectsjtangentially withflrespect to' the wall of the sound chamber ofthe whistle? 5 I i I In-Figs-gl to 1 inclusive, I haveshown one form'of construction or one method of gcarrying my invention into'eflect.

In Fig. '1,' I have shown a Whistle device of the detachable part whistle to awhistle;

comprising a substantially cylindrical sound chamber 10, and rojecting therefrom isa I mouthpiece part 11 arranged tangentially i with respect to thecha'mbe'r 10. .Inlthe con struction shown, the chamber 10 is formed from asub'stantially' circular wall '12 and fiat side walls 13, the latter extending onto the mouthpiece portion and the 11p extension 14 which iscontinuous with the wall 1 lyseen in'said'figure.

2 asclear "At 15, I have shownan insertpiece which I i is substantially V-shaped in form and is ar ranged in th'e-mouthpie cell todirectthe air upwardlyto a comparatively narrowmdischarge 16 into thesound chambertand. also chamber. by the curved extension'15f; .The'

circular wall terminates at its upper end as seen at 17 ata' point rearwardly of the cert- 'tral portion of thefchamber 10,- andldetachably mounted in" connection, withthe upper open endof the whistle structure is, a closure plate18 having at its rear end a rectangular, aperture 19 so arranged witherespect to the s complete theform'ation of the cylindrical device so as to retain the plate 18 against displacement. This structure is clearly seen in Fig. 3 of the drawing.

The rear end of the plate 18 is provided at its lower surface with an inwardly projecting flange or lip 22 which is adapted to extend beneath the wall 12 at itsend 1'? so as to support the inner end of the plate 18 against displacement, and further to provide a sea]. preventing the discharge of air from the chamber 10 except through the aperture 19. It is also preferred that the forward end .portion of the plate 18 be provided with an upwardly pressed and substantially V areshaped lip piece 23 which also forms a finger piece facilitating the removal of the plate 18v for cleaning or other purposes,it being understood'thatthe plate 18 is inserted and removed by, sliding the same forwardly and backwardly with respect to the whistle device.

It will also be understood at this time, that while I have indicated in the'several figures in the accompanying drawing, that-the parts of'the whistle device are made from sheet metal or other sheet material such as rubber, bakelite, celluloidand other materials of this class, that the several parts'constituting the whistle proper and the movable or removable member or plate may becast ormolded in accordance with conventional processes.

In F igs.'5 and 6 of the drawing, I have shown a slight modification, and in this figure, like references willindicate like parts,

the only structural difference being that the side walls 13 at the month end portion of thewhistle device aremade straight rather than inclined inwardly as inFig. 3, and the side walls of the plate 18 are correspond inglyformed. "Instead of slidably engaging pivot pins.

inner edge of the plate 18 instead of having, p the projecting lip 22, is provided with 'aslight the plate 18 with the whistle device, I pivot the same thereto at the mouth end portion of the whistle by forming inwardly pressed beads'or pivotsQt on the walls 13, and 25 on the walls 20 as clearly seen in Fig. 6 of the drawing, or these pivots may be made in any desired manner such as by the use of In this construction, the free bead or extension 26 which cooperates with theedge 17 of the wall 12 to frictionally retain the plate 18 infclosed position. i

In all forms of the whistle device, a ball 27 is arranged in the sound chamber of the 1 if whistle device and is'free to reciprocate there a supporting eye or loop 28 be attached to 7,

one wall'of the whistle body proper.

V In Figs. 7 and 8 of the drawing, I have shown another modification, wherein the sound chamber 10 of. the whistle device is modified in its construction in that the circular or cylindrical wall l2 'extends upwardly to form the contracted discharge 16 and also the inclined wall 29 0f the mouthpiece, which wall alsoconstitut'esthe bottom wall of said mouthpiece.

In this construction, the sidewalls 18 of the whistle device correspond to. the contour of the sound chamber and mouthpiece, said side walls at the mouthpiece end of the whistle devicebeingstraight as seen in Fig. 8 of the drawing; and their upper edgesare fashioned to form, on the inner faces thereof,

groovesBOtoreceive a top closureplate'31 which is slidably mounted in the grooves 30 in the operation of attaching and detaching the same, the inner end portion .of the plate 31 having an aperture82 which is similar to the aperture 19, and the inner end of said plate having a projecting lip 33 which rests under the Wall 12 to form a concealed joint at said end of the plate.

In Fig. 9 of the drawing, I have shown another modification which is substantially similar to the structure shown in Fig. 7 especially with respect to the general contour of the whistle'device. In'this structure, how--' ever, the sound chamber 34; consists of live angularly disposed side walls 35, 35 35, 35 and the wall .35 extending forwardly and downwardly to form the lower wall 35 of the mouthpiece 36, the chambers formed by straight. side walls 37 also-extending onto 1 and forming the side walls of the mouth piece 36. I i V WVith this form of whistle body structure, it will be seen that the same may be readilymolded, cast or even stamped from sheet material of any kind or class, especially in that the walls 35 and 35 extend upwardly-in a straight vertical line. In this construction, I employ a removable top closure plate 38 which is substantially'similar to the plate18 andincludes side walls 39 fashioned atithe mouthpiece end to conform with the'contour of the mouthpiece and dove-tailed as in the structure shown in Fig. 3, the inner end of the plate 38 having a downwardly eX-.

tending flange 4O whichbears against the wall 35. If desired, the upper end of said wall may be turned inwardly to a slight e2;- tent as seen at 41 to retain the plate 38 against displacement. This plate has a sound apertare/l2 arranged adjacent the contracted discharge 43 at the inner end of the mouthplece 36.
